SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 573,002, dated December15, 1896. Application filed March 2S, 1896. Serial No. 585,170. (Nomodel.)

To @ZZ whom, it may concern.-

Be it known that we, ROBERT KELSO and MORRIS RosENBAUM, citizens of theUnited States, residing at Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Safety-Pins, of which the following is a speciiication.

Our invention relates to a new and useful improvement in safety-pins,and has for its object to provide a device of this description in whichthe operation of disengaging the point of the pin from the guard will befacilitated, and a further object is to improve the manner of fasteningthe guard to the back section of the pin and provide a division-wallformed integral with the back section.

NVith these ends in view our invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, we will describeits construction and operation in detail, referring to the accompanyingdrawings, forming a part of this specification, and in which- Figure lis a perspective of a safety-pin made in accordance with ourimprovement; Fig. 2, a side elevation thereof, the guard being insection, illustrating the method of securing it in place 5 Fig. 3, anend view showing the guard forced to one side out of line with the pointof the pin, the normal position of said guard being shown in dottedlines; and Fig. 4, a similar view, the guard being forced to theopposite side.

In carrying out our invention we employ a single piece of wire, which isso bent as to form the pin-section A, a coil B, and la back section O,the latter being bent to produce the coils D and E at right angles toits length, and these last-named coils are wound in opposite directions,so that when the back section is twisted upon its axis these coils willact to impart resiliency to this movement either in the one direction orthe other, one giving the greatest efficiency in one direction 5o andthe other in the opposite direction The free end of this section O afterpassing from the coil E is bent to form a loop F, the inner end of whichis iiattened to serve as a partition G for guiding the point of the pinto the guard. II is a guard made of sheet metal and bent around aportion of the loop F and section O, where it is firmly held againstside movement by the ears I, projecting therefrom and bearing uponeither side of the partition G. 6o

From the above description the operation of our improvement will beobviously as follows: When the prong or section A has been insertedwithin the fabric for the well-known purposes,its point is guided to theguard by be- 6 5 ing forced against the partition Gr and permitting itto spring outward by the action of the coil B, and this is greatlyfacilitated by the fact that the guard may be sprung to one side or theother by exerting sufficient force thereon 7o to overcome the action ofone or the other of the springs I) or E, and when it becomes necessaryto disengage the point of the section A from the guard this isaccomplished by a reverse movement of said section and again springingthe guard to one side or the other in the saine manner as when securingthe pin. For some purposes this is of great advantage in that it isdifficult to spring the section A to either side when engaging ordisengaging 8o .its point from the guard, and another advantage of thecapacity of the guard to be sprung sidcwise is that the pin is notthrown ont of shape, as is often the case, by the wire of which it iscomposed being bent, since the resiliency of the coils D and E issufficient to prevent the setting of the wire.

Another advantage of the coils D and E is that they form a support tothe fingers when forcing the pin C into the fabric and in withoo drawingthe saine, the coil D being used. in forcing the pin into the fabric andthe coil E in withdrawing it therefrom. This is a great advantage overthe old form of safetypin, in which the back section usually clung fastto the fabric and was very difiicult of manipulation.

Having thus fully described our invention, what we claim as new anduseful is= A safetypin comprising the pin proper and .roo a back a coilformed at the junction of the back and the pin, coils on the back woundin opposite directions, a flattened extension of In testimony whereof Wehave hereunto af- 1o the back curved to form a loop, the end of ixed oursignatures in the presence of tWo said extension being,` reduced andbent up to subscribing Witnesses.
